I have built a custom kernel on xavier (using same config as the primary kernel), but I don’t know how or where to an entry for this kernel so that I can select it during boot. I no longer get the U-boot menu to select the kernel to boot from. I also realized that there’s no exlinux.conf file under /boot.
The developer guide that’s provided with the JetPack 4.0 EA has a mention about “how to build custom kernel” but doesn’t mention about configuring/booting with it. I saw mention of extlinux.conf in the “NVIDIA Driver Package Development Guide” under “Kernel Boot Time Optimization->Disable Console Over UART”.
Please let me know how to boot a custom kernel on Xavier.
